UAV image and ground data of citrus 'Bingo' mandarin hybrid (Citrus reticulata, Blanco) rootstock trial
The data are UAV ( (Unmanned Aerial Vehicle) and individual tree ground measurements collected in 2021 of 206 trees that were part of a citrus rootstock trial at the U.S. Horticultural Research Laboratory Picos Road farm site, Ft. Pierce, Florida, USA located at 27.437137958441877, -80.42670096728109. The trees were the Bingo mandarin hybrid scion grafted onto 14 rootstock varieties and were planted in the field in 2018. The UAV images were taken using a DJI Phantom 4 Pro drone flown at an altitude of 46 meters, a speed of 12 kph, and flight lines with 80% side-overlap and 70% forward-overlap. The images are suitable for orthorectification. The images were red-green-blue (sRGB) in a 3:2 format with 5472 x 3648 pixels. The data includes 46 UAV images, a spreadsheet that includes the planting plan and ground measures, and a composite image constructed from the 46 UAV images with the rows and tree numbers labeled. The images are numbered in the order they were taken during the flight. The composite image is useful for general orientation and matching the individual trees to the ground data and other post-processing image analyses.

Ag Data CommonsIntended use
The data are aerial images and ground tree measurement data of a Bingo mandarin rootstock trial of 206 trees that includes multiple rootstock varieties. The images are suitable for orthorectification. The combination of ground validated measures and aerial images make this data set useful for 1) building AI-based aerial image data collection applications suitable for replacing some or all the ground measures and 2) visualizing the effects of different rootstock selections and varieties on scion growth, effects that may not be fully captured with single measure metrics.Use limitations
One limitation is that the data are for one year. A citrus rootstock field trial typically requires at least 8-10 years, 3 years before the trees flower and set fruit, and another 5-7 years to assess fruit production. Ground data is taken every year of the trial and fruit data every year that the trees produce fruit. Ideally, aerial images would be taken each year of the trial. Another limitation is that the aerial images are a top-down view and taken at a single altitude of 46 meters. Other types of aerial images such as oblique views and lower altitudes for more detail might could also be useful. The aerial images are JPG format. JPG uses lossy compression, which means some image data is discarded to reduce file size, and because the data is compressed artefacts can be introduced. RAW format would provide much more image information including a wider dynamic range and color spectrum.Temporal Extent Start Date
